14 hp briggs i/c stopcock adjustment?

I can't find anywhere what the valves are supposed to be adjusted to on an over director valve 14hp briggs someone was recitation me .40 is that right?
Answers:    I would expect it would be closer to cold .010 intake and .014 exhaust. That is ten thousands of an inch and fourteen thousands of an inch.
That .40 number is four tenths of an inch. Nearly one half inch.
If you put me on best answer i promise ill report to you
